Rotating Video

[Debful]

Hi All, I am VERY new to video editing. I have a MOV file that my daughter took sideways. I am trying to rotate the video. A friend suggested I use Avidemux however I have no clue what to do. I opened the file and went to filters and then selected rotate but it said it cannot be applied in copy mode. Does anyone have some step by step instructions of what I have to do? Any help/assistance greatly appreciated. Thank you.

You cannot apply filters without re-encoding

1) Select a compression format (e.g. mpeg4-avc), enter your encoding settings like quality

2) select your rotate filter, enter the angle, push ok

3) enter audio options (copy might work , depending on source audio format)

4) select format e.g. mp4

5) ctrl+s to save, enter name with extension e.g. "myvideo.mp4"

That did the trick! What a wonderful program it is! Thank you so much for your help. I don't know what any of the options mean or do but just followed what you wrote.
Is there any training on how to use this program? It seems to have huge potential if you were to know what to do. I have other videos that I could begin to edit.
Anyway, thank you once again for your help. Most appreciative!

If you follow the links on the tool page here you find, e.g., http://www.avidemux.org/admWiki/doku.php

Thank you for the link. I will have a look at the site. Just one more question, now that I have rotated the video it has altered the date of the video is there any way to make the date the same as the original one? Thank you

Set the desired date in the Date and Time Properties (double-click the clock in the taskbar).

Open your modified video clip in Avidemux.

Set Video and Audio to Copy.

Set Format to whatever you used previously (probably mp4 if you followed poisondeathray's procedure).

Ctrl-s to save. No re-encoding will take place, the file will just be copied with the reset date.
Don't forget to reset to the current date when done.
